Sure. But to be honest: I do not own any Sam board. However both the
AmigaOne (not the X1000 variant) and the Sam boards use U-Boot as
firmware, make use of the same bootloader (AmigaOS's slbv2) and need
their own kernel image. So basically the same work has to be done for
these boards. That's why I would like to support the Sam boards, too.
BTW: Would this project be a candidate for Debian mentors? I don't
have much knowledge about the debian-installer yet and thus have a lot
of stupid questions, which are usually not answered on a dedicated
Debian mailing list.
